Currently (as of 1/20/2026), the Bates Numbering feature does not automatically update when pages are removed. This is a new bug that started as early as 1/16/2026, possibly due to an update. Before 1/16/2026, my company could take a PDF that was created and remove pages, then simply update the page numbers with one click. Now, Adobe doesn't recognize the Bates Numbering page numbers, and they are instead individual text boxes that have to be deleted and added back to change the page numbers.
